tstazn OF EIJGIN, ILLINOIS.

CLEANER AND SCBAPIER FDR FURNACE AND BOILER FL'UES.

Application filed. December 12, 1922.

To all whom it may concern:

Be it known that I, RALPH MAoGARri-n, a citizen of the United States of America, and residing at Elgin, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Cleaners and Scrapers for Furnace and Boiler Flues, of which the following is a specification.

This invention relates to improvements in cleaners or scrapers particularly adapted for cleaning or scraping boilers and their fines.

The invention has for its object, among other things or purposes, to provide for effectively and conveniently removing scale, soot and carbon or other adhering foreign material, from the boiler surface and the fines thereof or other parts of a boiler or furnace, also from the otherwise inconveniently accessible parts or locations of the boiler, or like instrtunentality.

The invention has also for its object to carry out the aforesaid ends or purposes in a simple, ready and expeditious manner, as will be seen from the following description and accompanying drawing.

The invention therefore consists of certain instrumentalities and features of con-- struction substantially as hereinafter more fully disclosed and defined by the appended claim.

Tie drawing illustrates the preferred or one form of my invention wherein it will be understood that various changes and modifications as to the detailed construction and arrangement of parts may be made without departing from the spirit of my invention as covered by the claim, and in which drawing,

Figure 1 is a plan view of my invention.

Fig. 2 is a side elevation of the same.

F 3 is a transverse section thereof taken on the line 3--3 of Fig. 2.

As characteristic features of my invention, I employ a scraper designated generally as 1, which may also be termed a rake, the same preferably comprising a longitudinal fiat or plate member 1 and transverse end members 1 and 1. One of the end members (1) is upwardly extended Serial No. 606,449.

and curved or rounded at its upper edge to conform to the curved rounded surface say, of a furnace, boiler or fine to provide for suitable engagement with the latter for the effective removal of the soot, carbon or other material adhering to the boiler or furnace surface, said end member being adapted to disengage the soot, carbon or whatever may have adhered to the boiler, furnace or tube engaged by said end member which thus serves as a rake or scraper.

The scraper 0r cleaner has a suitable preferably flexible handle 2, preferably composed of cables 2 Figure 2, wrapped spirally upon or around each other a suitable depth or thickness as shown, the handle member, thus formed, being secured. at one end within an orifice or socket formed in one transverse end member 1 and then passed through an orifice in the opposite end member and suitably extended therefrom, and provided with a hand-hold 3 for ready grasping in providing for the convenient actuation of the cleaner. The menr be r 2, is suitably clamped down upon the plate or longitudinal member 1 by means of an endfl anged and headed bolt or 'rivet 4;; and suitably connected to the member 1, with a link of each passed through an aperature in said member, as at 5, are chain or drag-members 6 adapted to normally or initially dangle or depend from the plate or longitudinal member 1. It is observed that the device suitably applied and manipulated by the hand-held 3 is arranged to impart a swishing movement to the chain or drag members, and the latter will be caused to engage the carbon, etc, accumulations so as to effectively dislodge or remove the soot, or carbon and clean out the boiler or furnace and that, as previously stated, otherwise heretofore inaccessible points are reached and cleaned out thereby.

In Fig. 1 is shown what I have designated as a pipe handled-member 2 which is preferably employed for boiler cleaning, while in Fig. 2, is shown what I have termed a flexible cable handled member, as adapted preferable for furnace cleaning.

1 claim A boiler, furnace or tube cleaner comsaid carrying member, also adapted to remove or dislodge the soot and carbon, the accumulations disengaged by said end member and dangling means being removed by said scraping and raking means.

In testimony whereof I aflix my signature.

RALPH MACCARTHY.
